I recently bought a facelift zed with 39k miles on it, with full nismo kit. The bodywork wasn't in great shape, it basically had a mark of some sort on every panel, but i bought it because it had a full service history and drove perfectly. It was what i wanted and i got it for a good price, just had it fully resprayed and its perfect now. Im not telling you to go out and buy a scratched up one, but like the others have said if it has a good service history and drives fine you shouldn't worry about buying a zed with higher mileage.
